Solved - setting font size for optimum reading

I have been bothered by the huge jump in font sizes between zoom levels 1 and 2 on the Aluratek Libre. On ePubs zoom 1 displays 31 lines of text and zoom level 2 displays 23 lines (using the serif font). I would like a font size in between these two. Here are the number of text lines for each zoom level:

Zoom 1 - 31
Zoom 2 - 23
Zoom 3 - 20
Zoom 4 - 18
Zoom 5 - 15
Zoom 6 - 11
Zoom 7 - 9

I played around with changing the base font size in Calibre. I found that if I set the base font size to either 8 or 10 the number of lines of text per zoom level is as follows:

Zoom 1 - 42
Zoom 2 - 31
Zoom 3 - 26
Zoom 4 - 24
Zoom 5 - 20
Zoom 6 - 15
Zoom 7 - 12

Whereas before there was only one step between 31 lines per page and 20 lines per page (zoom levels 1 - 3), by setting the base font size to either 8 or 10 you get two steps (zoom levels 2 through 5). I think this gives a more optimal range for choosing font sizes.

Of course this requires using the Calibre software which rules out DRM protected ebooks.

Good thinking, thanks for posting your results.
You might want to post to the Calibre forum as well, but be sure to mention the devices
it works for.

Luck;
Ken

Thanks, Ken -- I cross posted this to the Conversions sub-forum of the Calibre forum.
